The electricity trader "FlexPower" is expanding its business to include a new field of activity. A subsidiary is now taking over the development and operation of large-scale battery storage systems.

The expansion of large-scale battery storage systems is becoming a top priority for Flexpower: The Hamburg-based energy trading company has founded a new company, "Flexpower Energy", which will focus on the planning, construction and operation of grid-connected storage systems with a capacity of two to 50 MW.

According to the company, the subsidiary will take on traditional project development tasks and also operate storage projects itself. Marketing on the spot market and the provision of system-related services such as primary and secondary control power will remain the responsibility of the parent company.

Flexpower sees its new subsidiary as a platform for institutional investors and cooperation partners - from co-investments to independent development projects. Property owners are also to be addressed. According to the Hamburg-based company, this step is a response to the growing importance of flexibility in the electricity market. In view of volatile feed-in from renewable energy sources, the demand for storage solutions is high, the company emphasizes.

An initial project is already underway: A storage facility is currently being installed in Zeven (Lower Saxony). Flexpower Energy is planning storage projects with a total output of 510 MW and a capacity of around 1.2 million kWh by 2029. Sites in Lower Saxony and Bavaria are already being implemented.

Fabian Eckl and Amani Joas will take over the management of the new unit. Both also manage the business of the parent company "CFP FlexPower". Eckl refers to the price fluctuations in intraday trading: several hundred euros per MWh are not uncommon. In addition, there are rising prices for balancing power to stabilize the grid. "These price incentives show how important the provision of flexibility is in an electricity system that is now predominantly supplied by renewables," says Eckl.

Joas adds that the company is now deliberately investing part of the trading proceeds in physical storage infrastructure. The company is thus evolving from a pure trading company into a fully integrated energy supplier. The company already covers the entire chain from electricity generation and storage to supply. The company has also created its own trading platform called "PowerMatch" for this purpose. This enables standardized and transparent trading of all products along this chain.
